Abstract
The utility model discloses a low-pulse continuous outputting single roller hose pump which comprises a pump casing, a hose and a planetary roller assembly. A material inlet and a material outlet are respectively arranged on two sides at the lower end of the pump casing. The hose circles the circumferential surface of a pump cavity in a spiral shape, and two ends of the hose are crossed and then respectively connected with the material inlet and the material outlet in sealing mode. The planetary roller assembly is formed by a press roller and a spindle, the press roller is respectively fixed with crank discs on two sides in rotating mode through a fixing shaft, and the crank discs are fixedly connected with the spindle. The low-pulse continuous outputting single roller hose pump is stable in output, easy to maintain, long in service life and remarkable in practicality.
Description
Technical field
The utility model relates to a kind of industrial pump, relates in particular to a kind of single roller peristaltic pump of improvement.
Background technique
Peristaltic pump belongs to a kind of of peristaltic pump, has simple in structurely, without leaking, shears littlely, and fed sheet of a media is required the advantages such as low, and then very wide in the application of industrial media transportation art.Traditional peristaltic pump is typically provided with two or more pressure rollers and comes squeezing tube, and this peristaltic pump energy consumption is larger, and the flexible pipe frequency that is squeezed is high, and the life-span is short; The stream of pulses frequency that produces during peristaltic pump work is high and violent, and is larger on pump and delivery line impact; The single roller peristaltic pump that occurred afterwards is optimized roller structure, obtaining certain improvement aspect energy consumption, hose life and the pulse frequency, but owing to adopting single pressure roller, the time period of separating with flexible pipe in movement travel is longer, cause medium output to have " intermittently " property, do not reach effect stable, continuous conveying.In addition, the pressure roller of peristaltic pump usually adopts one-sided suspension structures in the past, and rotating shaft easily is out of shape behind the long time running, finally causes the pressure roller locking, can't normal rotation, and be transformed into sliding friction with flexible pipe by rolling friction, and flexible pipe or the pump housing are caused damage.
The model utility content
For overcoming above-mentioned technical problem, the utility model provides a kind of conveying stable, single roller peristaltic pump of the low pulse continuous wave output that the life-span is long.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of single roller peristaltic pump of low pulse continuous wave output, and it comprises:
Pump case has cylindrical pump chamber, and outer end cap adopts bolt to fix, and material feeding mouth, discharge port are separately positioned on both sides, pump case lower end;
Flexible pipe is arranged in the pump chamber, and it is in the shape of a spiral along the pump chamber side face circle that spirals, and two ends are tightly connected with material feeding mouth, discharge port respectively after intersecting;
The planetary rollers assembly is made of a pressure roller and main shaft; Pressure roller is fixing by the crank disc rotation of stationary axle and both sides, and crank disc is fixedly connected with main shaft.
The inboard circle centre position of the outer end cap of described pump case is provided with bearing support, and described front-end of spindle is provided with bearing, and is positioned at the bearing support of outer end cap.
Described flexible pipe infall still has the gap under squeezed state, described pressure roller length is enough to the flexible pipe infall is flattened.
The utlity model has following beneficial effect: because flexible pipe adopts said structure to spiral in pump chamber, the pump housing adopts single roller structure, produce a larger stream of pulses in circumference stroke of pressure roller, guarantee enough output quantities, reduced pulse frequency, pressure roller can be from quick, the mild transition of the starting point of flexible pipe in movement process, thereby realized stable, Non-intermittent output, reduce simultaneously the compression number of times to flexible pipe, in the life-span of having improved flexible pipe, prolonged continuous working period; The main shaft outer end is supported by outer end cap, and the pressure roller both sides are equipped with crank disc, has improved the stability of planetary rollers assembly, has prolonged its working life; In addition, owing to adopting single roll structure, reduced the consumption of oiling agent, made peristaltic pump be easier to safeguard.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 cuts structural representation open for part;
Fig. 3 is the outer end cap structural representation.
Embodiment
Shown in accompanying drawing 1,2,3, the utility model mainly by pump case 2, be arranged on flexible pipe 12 and planetary rollers module composition in the pump case 2.Be provided with cylindrical pump chamber in the pump case 2; The outer end cap 3 of pump case 2 adopts bolt 4 fixing, when peristaltic pump inside is safeguarded, outer end cap 3 can be unloaded; Outer end cap 3 inboard circle centre positions are provided with bearing support 13; Material feeding mouth 1, discharge port 5 are separately positioned on pump case 2 both sides, and are provided with flange plate, and material feeding mouth 1, discharge port 5 upper-lower positions are positioned on the horizontal tangent of pump chamber lower end; Flexible pipe 12 is positioned at pump chamber, and in the shape of a spiral along the pump chamber side face circle that spirals, two ends are tightly connected with material feeding mouth 1, discharge port 5 respectively after intersecting; Flexible pipe 12 infalls are reserved a fixed gap, must guarantee that infall still has the gap under squeezed state, prevent that flexible pipe 12 is overlapping, affect sealing; The planetary rollers assembly is made of a pressure roller 7 and main shaft 11, pressure roller 7 is fixing with crank disc 9 rotations of both sides by stationary axle 8, and crank disc 9 is fixedly connected with main shaft 11, and main shaft 11 tail ends are used for linking to each other with speed reducer, main shaft 11 front ends are provided with bearing, and are positioned at the bearing support 13 on the outer end cap 3; As its name suggests, pressure roller 7 is done planetary motion with main shaft 11 during work, cooperates to come squeezing tube 12 with the pump chamber inwall; Because there is infall in flexible pipe 12, pressure roller 7 length must be enough to flexible pipe 12 infalls are flattened.
The utility model adopts said structure, and when work, what pressure roller 7 was continuous is squeezed to terminal point with flexible pipe 12 interior media by starting point, then directly returns the starting point cycle rotation by terminal point, and then has arrived the purposes such as described low pulse, continuous wave output.
